論經濟報復措施的合法性

經濟報復措施為當代國際法所能接受的法律機制之一，其係脫胎於傳統國際法常用的單邊措施，但又異於傳統的概念。相較於傳統措施或片面自力救濟，以經濟報復措施反制他國，實有其必要性與合理性。國家基於主權平等原則與不干涉內政原則之前提下，應有裁量經濟報復措施的自由。但經濟報復措施不一定有侵入其他國家權利的性質，且可能對於特定國造成某一程度不利的影響，更遑論單方決定的性質意味著濫用，如何找出制衡點，一直是國際社會討論的重點。

An economic coercion is generally regarded as one of the acceptable legal mechanisms under modern international law. The measure originated in nations' unilateral measure which is common in traditional international law is different from that in traditional legal concept. Contrary to traditional means of settlement, using economic measure to counter other nations' behaviors demonstrates its necessity and rationality. A nation may take an appropriate measure freely under the doctrines of the sovereignty equality and independence, that is, national margin of appreciation doctrine. However economic measures do not necessarily mean to encroach on the rights of other countries and to have some adverse effects on other countries. Meanwhile, an unilateral discretion also shows the abuse of economic measure. Any countermeasure taken by the country shall be based under the principle of good faith. Thus, figuring out the equitable point has been the focus of recent discussion in international society.
